Question

(b) $(-8)^{\frac{1}{3}} = -2$
part 3 of 3
(c) $-8^{\frac{1}{3}} = \square$
(with interactive input options: $\square^{\square}$, $\sqrt{\square}$, $\sqrt\square{\square}$, $\frac{\square}{\square}$, not a real number, reset button, close button)

Explanation:

Step1: Rewrite exponent as root

$8^{\frac{1}{3}} = \sqrt[3]{8}$

Step2: Evaluate the cube root

$\sqrt[3]{8} = 2$

Step3: Apply the negative sign

$-8^{\frac{1}{3}} = -2$

Answer:

$-2$
